Application filed February 23, 190 6. Serial No; 302,649.

' To all whom it inay concern:

' and claimed.

Be it known that I, A BERT Pancoxs'na resident of New Kensington, in the county of Armstrong and State of Pennsylvania-have invented a new and useful Improvement in Dustproof Axle-Box Lids; and I-"do from plate metal, which is dust proof and which con; forms tothe standards of the Master Oar Builders Asso-' ciati on. v

The invention consists of details hereinafter described;

In the accompanyingdrawings Figure l a face view of my lid; Fig. 2 is a vertical section on theline 22, Fig. l and showing a portion of the axle box; Fig.

this flange extending continuously around the face of l is a horizontal section on the line 3'3, Fig. l; Fig. 4 1s a face view showing a modified form of lid; and Fig. 5' is a vertical section on the line 55, Fig. 4 and a'por- Lion of the axle box. I v

Theaxle. box is indicated at], this being provided with the usual perforated ear 2 for the pivot or pintle 3 of the lid and with the spring lug 4 having a spring bearing face which is substantially vertical, or at least inclined only slightly from the vertical.

The lid Sis formed of pressed-plate metal, such as steely and is provided with the usual hinge'ey-es'fi but has at its upper edge no hood for the spring due to the )fact that/the latter is on the outside. The lid--is provided with a continuous inwardly projecting rib or flange 'Z'iormed by pressing the metal inwardly, as shown, and arranged to enter the opening of the axle box and contact with the same at the top, bottom and both.si'des. Its edges also are flanged'inwardly asat 8,

the journal box at the bottom" and both sides, and at, thetop is modified so as to extend' underneath the spring. .At this point or opposite the spring lug 4 oi the box it may be reduced in width, as shown at 9, and made" to project up wardly as'weli as inwardly but it completely closes the opening at this point. Inas- "much as the lid has np-hood it'is possible to get this tight opening at the top as well as at the sides and bottom.

The spring 10 (or 10 Figs. .4 and 5) is applied to the outer face of the lid, being secured thereto either by a rivet 11, as shown in Figs. 1, 2 and 3, or by a stirrup rivet 12,115 shown in Figs. 4 and 5. Suitable ribs unite-pressed outwardly on the lid to confine the spring against swinging sidewise as might occur when only a single rivet is used. Such ribs will also preferably be used with the stirrup'shown in Figs. 4 and 5. With. such stirrup the lower end of the spring is provided with a shoulder 15 which prevents the spring from "falling downwardly and with. a hooked lower end: 16

which-prevents same from jumping up.

T e lidshowri in'Figs'. 4 and 5 is slightly modified at its top so as to fit the form of spring lug 4' shown in Fig. 5, This modification consists in bending the up,-

bearing and wear the same-out, as frequently happens with inside located springs. The external location of the'spring makes it easy to inspect as it is alwa'ys in sighbso that a broken spring'can be at once detected.

The inner and outer flanges give sufiicient friction on the axle box to hold the lid tightly shut on the axle box "even though the spring sho'hld break. These flanges furthermore, hold the lid properly in position even though there should be a large amount-of play on the pivot bolts. In fact it' is not necessary to fit these bolts tightly as the flanges necessarily position the lid.

' "per flange of the lid outwardly on an incline, as shown at 17, to fit said lug. i

Consequently the holes in the hinge can be made by coring and do not need to be machined.

' The lid he a whole is cheap of construction, exceedingly stron' 'g, dust proof, and conforms to. the Master Gar Builder'slstandards, and can be readily adapted to any form andssize' of axle box.

What I claim is: p v

1- An axle hox lid interchangeablewith the Master Qar Builders'- standard lid, having hinge eyes at its upper end and with a hinge lug opening between said hinge eyes, and provided with continuous inwardly proJecting flanges at its siflennd bottom edges and with an upwardly projecting flange atits upper; edge extending uninterrnptedly between the hinge eyes. said side and bot-tom flanges being arranged to encircle the outside or the axle box opening. and the upper flange being arranged to bear with its side face against the outer upwardly extending fur-e nfthe hlnge lug of the Blaster Car Builders standard axle box, and n leaf spring secured to said lid.

2; An axle box lld luterchnngenble with the Master (nr Builders standard lld, halving hinge eyes at its upper end and an opening for thc hlngo lug between said hingeeycs and provided with continuous inwardly projecting flanges at itslide 1nd bottom edges and with an upwardly projecting flange at its upper edge extending uninterru'ptediy oem" the hinge lug opening. said side and bottom flanges i being arrsnfied to encircle the outside 01 the axle ho: waning and the upper flange being nrrunged to bear with its side race against the outer upwardly extending face of the hinge lug 01 a Master Car Builders standard axle box; skid lid also having a continuous inwardly projecting rib inside of its edges and extendingnlong the top, bottom and both sides and arrnnged to enter the axle box opening, and

.d lee! spring secured to said lid.

' ti. An axle box lid interchangeable with the Master Car Builders standard lid, having hinge eyes at its upper end with an opening for the hinge lug between said eyes, and provided with continuous inwardly projecting flanges at its side and bottom edgesjnd with an upwardly projecting flunge'at its upper edge extending uninterruptedly across theopening for the hinge lug, said side and bottom flanges being-"ranged to encircle the outside 0! the axle box open in; and the upper flange being erra'nged to bear with a side lace lgainlt' the outer upwardly extending face or the aoopos hinge lug ot a Master (lar Builders standard axle box, and a lent spring secured to the outer face of said lid.

4. A dust proof axle box lid interchangeable with the Master Car Builders standard lid, having hinge eyes at its upper end with an opening for the hinge lug between, said eyes, and provided with continuous projerting flanges units side and bottom edges und with an upwardly in ciined flange at its upper edge extending uuiuterruptedly across the opening for the hinge lug said side and bottom liangos being arranged to encircle the ouiside'of the axle box opening, and the upper flange being arranged to bear with a side tnce against the outer upwardly extending face at the hinge lug o! a Master (far Builders standard uxie box, said lid having projections on its outer face. and a lent spring secured to the outer face of the lid and lying between said projections.

In testimony whereof, I the suid'ALm-nrr PANCOAS'L have hereunto set my hand. 7
